Wow, you caught it just at the right moment of sheer delight! she is practically flying with joy! My oldest son has been bring home big boxes this summer to make houses for his boys… they love them of course.. but the youngest one, the 2 y/o is Mr. Destructo and is also very strong… so they do not last very long… his older brother is so patient in comparison & is so sad when he doesn’t have his house after 10 minutes of play!
